Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30338, here are decompositions:

19 + 30319 = 30338
31 + 30307 = 30338
67 + 30271 = 30338
79 + 30259 = 30338
97 + 30241 = 30338
127 + 30211 = 30338
151 + 30187 = 30338
157 + 30181 = 30338

Showing the first eight; more decompositions exist.
